Patent GB-382858-A (GB)
Title: Improvements in or relating to safety devices for internal combustion engines
IPC: F01L13/00
Filed: 1932-03-14
Abstract: 382,858. Fuel-injection pumps. KRUPP GERMANIAWERFT AKT.-GES., F., Gaarden, Kiel, Germany. March 14,1932, No. 7505. Convention date, March 17, 1931. [Class 102 (i).] During the starting of an internal-combustion engine by compressed air, the suction valve O of the fuel-injection pump L is held open until the engine has attained a suitable speed. For this purpose a pump A, which may be the lubricating pump, driven by the engine crank shaft, supplies liquid to a cylinder C, the plunger D of which is linked to a lever E on a spindle F. An eccentric G on the spindle F forms the pivot of a lever, which is operated by the pump cross-head, and lifts the stem of the valve O through a tappet N, when the lever E is depressed by a spring K. When the lever E is raised by the plunger D the valve O is allowed to close. Liquid from the pipe B returns to suction through a pipe J past a loaded valve H. In a reversing engine a three-way cock, operated by the reversing- gear, controls the connection of the cylinder L to the pressure side of the pump.

Title: Remote control arrangements
IPC: B60T13/66
Filed: 1971-03-23
Abstract: 1384053 Position encoder; brake control system WESTINGHOUSE BRAKE & SIGNAL CO Ltd 3 March 1972 [23 March 1971] 7552/71 Heading G4H [Also in Division F2] A vehicle brake control apparatus includes a brake control device 1 which may be set to any one of a range of positions according to a desired braking effect, coding means 5, 6, 7 responsive thereto, a pulse generator 16, a binary counter 15, a comparator 18, and conductors 24, 25, 26 leading to braking apparatus. As shown in Figs. 1 and 2, which are composite parts of a single diagram, the shaft 3 of a driver's rotary brake handle 1 carries three metallic vanes 4a, 5a, 6a which are in the form of discs with selectively removed portions. Each vane co-operates with one of three solid-state oscillators 5, 6, 7, the assembly thus far constituting a Gray code device having eight positions and such that the combined output from the oscillators changes by only one unit for unit displacement of shaft 3. The outputs of the oscillators are rectified internally and applied respectively to inverting Schmitt trigger circuits 11, 12, 13. The digital codes therefrom are fed to a "Gray-to-binary" code converter 14 which provides outputs A, B, C, and "not" outputs A, B, C. An up-down digital counter 15 counts up or down in response to pulses derived from a clock pulse generator 16 via a clock pulse gate circuit 17. The gate circuit 17 is controlled by outputs derived from a comparator logic circuit 18 which compares the digital outputs from counter 15 with those from the Gray-tobinary code converter 14. A gate 19 controlled by "not" outputs A, B, C causes circuit 17 to inhibit application of pulses to counter 15 when a count of 000 is reached, and a gate 20 controlled by outputs A, B, C causes circuit 17 to inhibit application of pulses to counter 15 when a count of 111 is reached. Outputs A, B, C from counter 15 are also applied through amplifiers 21, 22, 23 to conductors 24, 25, 26 which lead to digitallycontrollable fluid-pressure-operated rail-vehicle braking apparatus such as that shown in Specification 903,600. In operation, brake handle 1 is set to a position corresponding to a desired braking effect, so the output of converter 14 corresponds to a "braking demand" code. The comparator 18 compares this with the output which for the time being exists at counter 15 and controls gate circuit 17 which supplies "up" or "down" signals as necessary to counter 15. The rate of change of code output from counter 15 is governed by the pulse rate of clock pulse generator 16, which is independent of the rate at which handle 1 is operated, so the apparatus provides an effective "jerk control". Means may be provided for connecting the amplifiers 21, 22, 23 directly to the Gray-to-binary code converter 14 so that in the event of malfunctioning of, e.g., counter 15, the "jerk control" may be over-ridden.

Filed: 1938-03-11
Abstract: 512,645. Hydraulic shock-absorbers. NEWTON, N. B. March 11, 1938, No. 7558. [Class 108 (iii)] In an hydraulic shock-absorber of the kind in which an extension g of the piston rod i is provided on the remote side of the piston h so as to maintain a constant volume within the cylinder a, the extension g is flexibly connected with the piston h, e.g., by means of a universal joint, so that it is capable of disalignment with respect to the rod i, thus preventing binding of the piston under lateral stresses. As shown, the end of the extension g is provided with an annular groove w<1>, fitted with a two-part spherical ring w, which is adapted to work in a corresponding divided part-spherical socket s mounted in an adjustable head r of the piston. A slight play is permitted between the groove w' and ring w, and a small adjustable gap s<1> is left between the two parts of the socket s, so that the extension g is capable of both lateral and angular displacement relatively to the rod i. The flow of fluid through the piston is controlled by a spring-pressed sliding valve o in the piston-rod i, and by a spring-loaded plate valve l co-operating with passages k in the piston, while the bulkhead b has passages controlled by ball valves f. Specification 501,516 is referred to.

Title: Improvements in or relating to liquid pressure controlling mechanism, particularly for aircraft
IPC: B64C25/22
Filed: 1935-03-16
Abstract: 448,478. Reciprocating pumps. AUTOMOTIVE PRODUCTS CO., Ltd., and BROWN, F. V., Brock House, Langham Street, London. March 16, 1935, No. 8250. [Class 102 (i)] [See also Group XXIX] In hydraulic operating or controlling mechanism for brakes, guns, and for the undercarriage, tail wheel, or other parts of aircraft, an operating lever or equivalent serves both for actuating a manual pump and for controlling the direction in which the receiving cylinder unit is actuated by liquid delivered from a mechanical pump. In the arrangement shown in Fig. 2, a handle 24 operates the pistons of a pump B through a spindle 23 and rocker 22. When a knob 25 is turned in one direction or the other it acts through rods 26, 27 to allow a valve 28 or 29 to close, and the pump then draws liquid from a reservoir A and delivers it through a pressure chamber 30 or 31 and a pipe 35 or 36 to one or other end of a cylinder E, liquid forced out of the other end returning through the open valve 28 or 29. When the knob 25 is in mid-position both valves 28, 29 are held open, and the pump is byepassed. The spindle 23 also actuates a rocker 40 adapted to act on the balls 43, 44 of a selector valve C. When the handle 24 is in mid-position both ball valves are held open, and a mechanically driven pump D is byepassed. With the handle in an extreme position one or the other ball valve is open with the other closed, and the output of the pump D passes through and past a non-return valve 48, 49 into the pipe 35 or 36. In the manually actuated pump shown in Fig. 3, the handle 24 for actuating the pistons through the rocker 22, encloses a rod 58 connected to the knob 25 and formed with a pinion 56 meshed with a rack on a member 53. Axial movement of the latter turns a rod 55, so that a pin 64 or 65, Fig. 5, acts on a cam surface on a movable collar 60 or 61 to allow closure of the valve 28 or 29. The spindle 23 has notches engaging a pin 70 carried by the rocker 40 which operates the selector valve C of the mechanically driven pump. Specification 428,252 is referred to.
